Blitz Dual TT.... supply/tool prep... ebrake? alarm? lighter instead?

[Pkay]

Searched all the millions of Blitz Dual TT threads still have a few questions and some possible brainstorming and what not. Mine will be here friday so wanting to be ready and what nto.


1) Is there anything NOT in the box that is reccommended supply wise? If so what

2) What is the purpose of the E-Brake release shutoff wire? Still confused on that one

3) On the alarm..... do I understand correctly most have tapped into the constant line which is in series with the alarm? Doing so makes it so you can't enable the alarm until after the "cool down" period when the TT turns off?

4) Has anyone used the cigarette lighter as their constant? I know a similar issue with the alarms arose for the 3rd Gen Rx7's and the solution was to tap into the lighters feed and use that. Thoughts?


thanks in advance for any help

 

[t3ase]

I can answer a few of these...

2) What is the purpose of the E-Brake release shutoff wire? Still confused on that one

Scenario: After installing the turbo timer, you decide it's time to go to a friends house and relax a while. You turn off the car and the turbo timer starts it's countdown, say 45 seconds. While you're inside, Mr. Mazda Thief comes to your car and sees that it's still running. Mr. Mazda Thief breaks the window, gets in, puts his foot on the clutch and grins. He looks over and releases your parking brake only to have the car shut off on him the moment he does that. Mr. Mazda Thief gets pissed off and leaves.

3) On the alarm..... do I understand correctly most have tapped into the constant line which is in series with the alarm? Doing so makes it so you can't enable the alarm until after the "cool down" period when the TT turns off?

It's not so much as to where it's wired, it's just that the car thinks it's still running. Ever try to arm your car or hit the panic button with the keys in the ignition only to have it not do a thing? That's the same thing. The car's still running, so the alarm refuses to do anything.

 

[Pkay]

right.... so I'm wondering if instead you hook it up to the lighter (which is on when your car is and off when your car is) if that'd work. Well I know it'll work power wise but do I understand correctly the dual TT has a count down of its own?

For a normal pod boost gauge the lighter is always the best place to take your feed but then again they don't need a countdown of any sort etc etc.



anywho thanks for the response

i'm an electronics engineer so if it's possible I'll figure it out eventually... might just need to wait for the unit.

As far as your whole lighter scenario goes...I'm not sure. I don't think it's as much as where the TT constant is tapped into, but more where the alarm constant is tapped into. I'm not sure where the alarm is wired, but I think that location determines if you can set the alarm with the car running or not. Do you follow what I'm saying?

TT wire - doesn't matter where it's tapped into, as long as it's a constant 12v power supply.
Alarm wire - determines if car runs or not.

incidentally - My timer function didn't work at all until I tied into the ebrake line.

 

[Pkay]

Is the problem that the dual tt still uses power after the car is off for the cool down period?

The problem is not with the Constant 12v, it is with the Ignition 12v. The solution the RX guys came up with is to tap the cig lighter for the alarm's Ignition 12v because the cig lighter is on the Accesory 12v feed in the RX. I do not know if this is the case in the Pro. If it is, then it is a simple solution to the problem, although you still get into the problem of the shock sensor activating when the car shuts down. I may give this a shot and see if it is a fix, I did it on my buddy's 3rd Gen and it worked fine.
Certainly a lot easier thant he solution I came up with before.

To add - So as the TT supplies 12v to the car's Ignition, the Accesory 12v is off, hence the alarm thinks the car is off, so you can arm it while the TT is running.

The last question is, the TT has an Accesory 12v output, I have always wondered why? I will do some experimentation later,

So ye or nay...... instead of tapping into the ignition shall I try the cig lighter?

TT will turn on once key is turned and will turn off once key is turned off. Thus should be able to arm alarm as once key is off TT is off and alarm is untouched.

ok man,
keep us posted on all your experimentations, i am very interested.

Huh???
Not sure if I follow you, but if I do, When you take the key out, the timer turns off? Wouldn't that defeat the purpose of the turbo timer?

 

[Pkay]

thats my question.... does the turbo timer need to be on after ignition is killed? Or is it only needed while car is running.... im unfamiliar with the dual TT

 

[Kenetix]

Its only needed when the car is running.

 

[blynzoo]

Its only needed when the car is running.

Survey says!!!!!

Um, niether.

The TT keeps the car ON after you have turned the ignition to the OFF position. Once the timer has run (say 45secs), it then turns the car off itself. This allows you to remove the keys from the ignition and arm the alarm while the engine runs to allow the turbo to cool down.

The TT will need to be wired to a constant 12V source because it must run after the ignition 12v is off. Its power source will be the same as an alarm, which also runs of constant. The difference is the alarm must be able to arm with the engine "running." By wiring the alarm sensor to the ignition, you can tell it the car is off when in fact the TT still has it running.

Someone already posted that, just cleaning it up a bit.

Brook, I am sure you meant wiring the alarm Ignition input the Accesory, which are two different things. If you wirht he alarm to ignition while the TT is providing 12v to the ignition, the alarm thinks the car is still on.

I will rewire the TT after my son gets picked up at 2:30 PST, I will post a definitive answer then.

From the accessory line on the TT? Okay. Unfamiliar with how the Blitz works. Cool.

I am not sure how the alarm is wired. In the porsche turbo that we wired, you could tap the physical ignition in the column (not the ignition system that fires the plugs) and allow the alarm to arm whenever the key itself was turned to off.

Thanks for clearing ME up! (thumb)

Okay here is your answer.

The alarm is not a stand alone module. It does not receive the signal from the remote. It is integrated and activated by the keyless entry module located by the firewall. The remote still unlocks and locks the doors without the alarm brain being plugged in.

This being said - I WAS WRONG IN MY EARLIER SUGGESTIONS AND IDEAS ABOUT HOW TO MAKE THE ALARM WORK WITH THE TT.
Wheh! My therapist said I was close to a breakthrough...

The only way it can be done is to modify the keyless entry module wiring to allow operation of the remotes with the 12v on the ACC line. THe keyless has a lockout mode where it will not allow operation while the car is on. This is why when we turned dipswith 2 to the on position, we got alarm on, but no doorlock. This I am not willing to do to my car.

I put more time and effort into understanding the way the system worked this time, where before I had responded on how I thought the system worked. For this, I apologize.

At this time, I do not see any way for any TT to operate and allow the factory alarm system to work simultaneously. This certainly does blow.

Sorry to be a pain in the ass mod, but we are trying to clean up all the forums to make it easier to search for items, and less cluttered. In the future, please post in the appropriate forum...example - Intakes, dispite being for the Mazdaspeed, belong in the performance section. Buying a carbon fiber hood for your Mazdaspeed belongs in the Appearance section. If you raced someone in your Mazdaspeed it still belongs in the Racing/Motorsports section. If you have any questions, comments, or complaints, feel free to PM me at any time.

Thanks again for your patience as we clear up the forums to make it better for you!
